I have never had an issue with mine, are your hoses too long? Mine run from the bucket up through the opening between the left hand lift arm and tilt ram and up to the quick couplers. The hoses don't go anywhere near the wheels.
I have a 751 C and when I got my combo bucket, it came with a bracket that attaches to the lift arms near the bottom pretty much right in front of the tire. This loop bracket guides the hoses and prevents contact with tires. Even with this bracket, the hoses are very close to the tire. The way it sits I could not use tracks due to lack of space. The bracket is a bobcat supplied item.
